The Cuban Model for Higher Education of Older Adults: Generativity,Social Commitment,and Collaborative Work     

José Alberto Yuni  Claudio Ariel Urbano 《Educational gerontology》2013,39(10):715-722

The present work is an approach to study the Cuban model for educating the elderly, and its aim is to describe the main features of the experience developed by this country. The University of the Third Age is more than three decades old in Latin America, but none of the countries in the region can show a state educational policy regulating and orienting its development. Cuba is the only country that has designed an educational program for older adults at a national level. The model is the most outstanding one among the rest of the countries in the American continent. This research is based on documentary analysis and interviews held with leaders and managers of the Chair for Older Adults, who were located in different towns of Cuba. Results led to a reconstruction of a set of dimensions of the Cuban model, such as the process of institutionalization, syllabus organization, the process of expansion and universalization, and educators' training strategies for elders. Finally, bearing in mind the features of Cuban political organization and gerontological positions, it was possible to draw the future evolution and challenges faced by the Cuban model for educating older adults.  相似文献   

Reminiscence Effects on Inter- and Intra-Individual Differences in Pursuit Rotor Performance

Abstract

Sixty male college students were given sixty 15-sec. trials on the pursuit rotor learning task. Practice was interrupted halfway through learning by a 10-min. rest period in order to investigate whether or not a reminiscence effect would influence inter-individual differences and intra-individual variation in performance. Results were consistent with previous experimentation in that inter-individual differences increased as a result of both practice and the interpolated rest period. A corresponding effect on intra-individual variation was barely noticeable.  相似文献   

Saint Matthew strikes again: An agent-based model of peer review and the scientific community structure     

Flaminio Squazzoni  Claudio Gandelli 《Journal of Informetrics》2012,6(2):265-275

This paper investigates the impact of referee reliability on the quality and efficiency of peer review. We modeled peer review as a process based on knowledge asymmetries and subject to evaluation bias. We tested various levels of referee reliability and different mechanisms of reviewing effort distribution among agents. We also tested different scientific community structures (cohesive vs. parochial) and competitive science environments (high vs. low competition). We found that referee behavior drastically affects peer review and an equal distribution of the reviewing effort is beneficial only if the scientific community is homogeneous and referee reliability is the rule. We also found that the Matthew effect in the allocation of resources and credit is inherent to a ‘winner takes all’ well functioning science system, more than a consequence of evaluation bias.  相似文献   

Isokinetic hamstrings-to-quadriceps peak torque ratio: the influence of sport modality, gender, and angular velocity     

Andrade Mdos S  De Lira CA  Koffes Fde C  Mascarin NC  Benedito-Silva AA  Da Silva AC 《Journal of sports sciences》2012,30(6):547-553

The purpose of this study was to determine differences in hamstrings-to-quadriceps (H/Q) peak torque ratios evaluated at different angular velocities between men and women who participate in judo, handball or soccer. A total of 166 athletes, including 58 judokas (26 females and 32 males), 39 handball players (22 females and 17 males), and 69 soccer players (17 females and 52 males), were evaluated using an isokinetic dynamometer. The H/Q isokinetic peak torque ratios were calculated at angular velocities of 1.05 rad · s?1 and 5.23 rad · s?1. In the analysis by gender, female soccer players produced lower H/Q peak torque ratios at 1.05 rad · s?1 than males involved in the same sport. However, when H/Q peak torque ratio was assessed at 5.23 rad · s?1, there were no significant differences between the sexes. In the analysis by sport, there were no differences among females at 1.05 rad · s?1. In contrast, male soccer players had significantly higher H/Q peak torque ratios than judokas (66 ± 12% vs. 57 ± 14%, respectively). Female handball players produced significantly lower peak torque ratios at 5.23 rad · s?1 than judokas or soccer players, whereas males presented no ratio differences among sports At 5.23 rad · s?1. In the analysis by velocity, women's muscular ratios assessed at 1.05 rad · s?1 were significantly lower than at 5.23 rad · s?1 for all sports; among men, only judokas presented lower ratios at 1.05 rad · s?1 than at 5.23 rad · s?1. The present results suggest that sport modality and angular velocity influence the isokinetic strength profiles of men and women.  相似文献   

Laser scanning and digital imaging for the investigation of an ancient building: Palazzo d’Accursio study case (Bologna,Italy)     

Arianna Pesci  Elena Bonali  Claudio Galli  Enzo Boschi 《Journal of Cultural Heritage》2012,13(2):215-220

This paper describes a scientific approach aimed at studying the ancient part of Palazzo d’Accursio (Bologna, Italy), a masonry building which is part of the Italian cultural heritage. Laser scanning and the inspection of digital images are used to detect traces of restoration works and other interesting features related to both architectural marks and natural or anthropic events. One of the main elements of the method is the analysis of residual maps, obtained by computing the differences between the point coordinates of the façade and reference fit planes. The obtained results, based on both radiometric and geometrical analysis, are used to provide a reasonable hypothesis as to the original configuration of the studied building, while taking into account the available historical information about the constructive phases of the building.  相似文献   

Effects of weightlifting exercise,traditional resistance and plyometric training on countermovement jump performance: a meta-analysis     

Ricardo Berton  Manoel E. Lixandrão  Claudio M. Pinto e Silva 《Journal of sports sciences》2018,36(18):2038-2044

Jump performance is considered an important factor in many sports. Thus, strategies such as weightlifting (WL) exercises, traditional resistance training (TRT) and plyometric training (PT) are effective at improving jump performance. However, it is not entirely clear which of these strategies can enable greater improvements on jump height. Thus, the purpose of the meta-analysis was to compare the improvements on countermovement jump (CMJ) performance between training methods which focus on WL exercises, TRT, and PT. Seven studies were included, of which one study performed both comparison. Therefore, four studies comparing WL exercises vs. TRT (total n = 78) and four studies comparing WL exercises vs. PT (total n = 76). The results showed greater improvements on CMJ performance for WL exercises compared to TRT (ES_diff: 0.72 ± 0.23; _95%CI: 0.26, 1.19; P = 0.002; Δ % = 7.5 and 2.1, respectively). The comparison between WL exercises vs. PT revealed no significant difference between protocols (ES_diff: 0.15 ± 0.23; _95%CI: ?0.30, 0.60; P = 0.518; Δ % = 8.8 and 8.1, respectively). In conclusion, WL exercises are superior to promote positive changes on CMJ performance compared to TRT; however, WL exercises and PT are equally effective at improving CMJ performance.  相似文献

The Influence of Coaching on Employee Performance: Results From Two International Quantitative Studies     

Claudio Pousa  Anne Mathieu 《Performance Improvement Quarterly》2014,27(3):75-92

Coaching has been identified as a key managerial behavior that organizations must promote to develop employees and achieve higher levels of performance. Despite this agreement and an increasing interest in coaching, there is still a paucity of studies exploring the impact of coaching on individual performance. This article presents an empirical investigation from two international field studies, one using business‐to‐business salespersons working in Latin America and the other one using business‐to‐consumer frontline employees from a service organization in Canada. Building on leader‐member exchange theory, we propose that coaching increases individual performance beyond the potential impact of sales experience and tenure. We find that coaching can explain between 2.9% and 6.2% of the variance in performance when controlling for tenure and experience. This article makes several scientific and managerial contributions, and also opens new avenues for research.  相似文献
